Horizontal line label

I would like someone to develop a "Horizontal line label" indicator similar (if not almost exactly) like the one I use in NT7. Essentially, the indicator is able to recognize either computer or user generated horizontal lines plotted on the chart and creates a price label coincident on the rightmost side of the chart along the y-axis. In the attached screen shot you will see the labeled lines. These labels are plotted via the Horizontal line indicator highlighted in blue in the second screen shot, however, the indicators which plotted the actual lines are different. The Horizontal line indicator identifies horizontal lines and merely tags them.
